The PRE-73 MKIII is a one-channel vintage style microphone-, line- and instrument preamplifier. The signal path uses only discrete components like resistors, capacitors and transistors. The in- and output is transformer balanced, using two different transformers, each one optimized for its purpose. This is the way audio components were built before integrated circuits became available.

The circuit used in the PRE-73 MKIII is similar to the preamp section in the classical 1073 module with a corresponding sound character that is warm, punchy, sweet and musical. These classic characteristics have been heard on countless recordings through the years and it is a versatile sound that works very well on most sound sources and in most genres.
The essence of this sound is now available at a surprisingly low cost, making it available to nearly everyone.

Features  :

• Vintage Style electronics. No intergrated circuits in the signal path.

• Maximum gain in MIC mode is 80 dB, enough to handle passive ribbon mics with quiet sound sources.

• GAIN switch range 20 - 80 dB. GAIN/LINE mode switch, gain is reduced by 30 dB in LINE mode.

• Selectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHz.

• Selectable 6 dB/octave two frequency high pass filter at around 40 (HP1) and 170 Hz (HP2).

• Tantalum capacitors in the signal path.

• Switchable impedance in MIC mode, 1200 or 300 Ohms, will change the tone of most mics. The input impedance in LINE mode is 10 kohm.

• Switchable phantom power and absolute phase.

• A high-impedance instrument input for any sound module, electric guitar or bass.

• A simple but effective 4-step LED output level meter.

• The output level control makes it possible to make fine gain adjustments and also to overload the main gain stage(s) for more character and then lower the signal to a suitable level before the output stage.

• Combo XLR/TRS input jack and separate output XLR and TRS jacks for flexible connections.

• Insert jack for inserting EQ´s and other units.

• Selectable 600 ohm output termination.

• The pcb is prepared for the Carnhill input transformer.

• External power supply to avoid interaction with the audio circuits and transformers.

• A solid build quality that will last many years of normal use.

The MKIII has the following new features compared to the MKII:

• Tantalum capacitors in the signal path.

• Selectable two position high frequency AIR boost eq, 3 or 6 dB @ 30 kHz.

• Selectable two frequency high pass filter, 6 dB/octave at 40 or 170Hz.

• The pcb is prepared for the Carnhill input transformer.

• Revised and less complicated GAIN switch with a separate switch for MIC/LINE selection.

• All GAIN settings can also be used in LINE mode .

The PreSonus HP60 is the most flexible and advanced headphone amplifier system available for professional and project recording studios as well as live sound in-ear monitoring systems. Loaded with six independent,
loud and clear headphone amplifiers, the HP60 features dual stereo inputs as well as external input, for each
channel allowing you to mix between three stereo audio streams (mix A, mix B, and external input). Stereo output is also available on each channel to send line level headphone channel mixes to additional headphone amplifiers or monitor systems. Each channel features headphone level, mix control between A and B inputs, external input volume, mute and mono. The HP60 also features talkback via external XLR microphone input. Common set up of the HP60 in a recording session is to send the main control room mix to input A. Send the click track to input B. Send the each band member direct recording input to each channelʼs external input (more me). This will allow each band member to create a mix between the main mix, the click track and themselves. The HP60 is the ultimate headphone amplification system delivering loud and clear headphone mixes for real-world recording situations.

Features:
-Six independent ultra low noise, high output headphone amplifiers (150 mW per channel)
-Two sets of stereo inputs (A and B) with balanced TRS connectors
-Stereo external input point on each channel for "more me” with trim control
-Mix control between inputs A and B
-Talkback with external XLR microphone with control
-Direct stereo line output on each channel

Behringer MIC-2200 2-Channel Tube Microphone Preamplifier-Line Driver-DI Box

The MIC2200 is the ideal extension to your console, MIDI setup or hard disk recording system. Its integrated parametric EQ?s give you extra sound-shaping power, while its built-in tube adds warmth and transparency to your signal. In addition, the ULTRAGAIN PRO features direct injection and level conversion functionality.

PreSonusʼ popular Class A XMAX preamps are widely lauded for their clarity and transparency. Our tube preamps are beloved for their warm, smooth sound. With the Blue Tube DP V2 dual-path mic/instrument preamp, you get both types of high-quality sound in one unit.

Now weʼve improved on the classic unit with the BlueTube DP V2. The solid-state path now feeds PreSonusʼ top-of-the-line Class A XMAX™ mic preamplifier with 80 dB of variable gain—an upgrade from the original BlueTube DPʼs solid-state stage.

You still get all the secondary features you expect in a professional-grade preamp: 48V phantom power, an 80 Hz high-pass filter, -20 dB pad to control hot input signals, and a polarity-reverse switch. Each channel has an illuminated VU meter so you can visually monitor your input levels.

A Tube Drive control provides a wide range of sounds: when itʼs clicked off, youʼre using the solid-state preamp for quiet, transparent amplification; when itʼs engaged, your signals flow through the tube preamp, and you can achieve anything from gentle warmth to edgy distortion.

    2 input channels, each with:
        High-headroom Class A XMAX™ mic preamplifier with 80 dB gain range
        12AX7 vacuum tube gain stage
        Tube Drive tube-saturation control
        48V phantom power
        80 Hz high-pass filter
        -20 dB pad to reduce hot input levels
        Polarity-reverse switch
        Illuminated analog VU input-level meter

    Input/Output
        2 balanced combo mic/unbalanced instrument inputs
        2 balanced XLR main (L/R) line outputs
        2 unbalanced ¼” main (L/R) line outputs
